The EN 1092-1 Type 11-B Weld Neck Flange is a high-performance piping component engineered for demanding industrial environments. Featuring a distinctive long tapered hub (Type 11) and a Raised Face (Type B), this flange is designed to be butt-welded directly to the pipeline system, ensuring exceptional structural integrity, smooth stress distribution, and secure sealing under high-pressure and high-temperature conditions.
Tapered Hub Design: The long, gradually sloping neck transfers stress smoothly from the flange to the pipe itself, significantly reducing high-stress concentrations at the base.
Raised Face (Type B Sealing Surface): Enhances sealing efficiency by concentrating bolt loading onto a smaller gasket area, creating a reliable, leak-proof joint.
Full Penetration Butt-Welding: The welding joint allows for radiographic testing or non-destructive examination (NDE) to verify internal weld quality.
Wide Pressure-Temperature Ratings: Available across standard nominal pressure classes (ranging from PN 2.5 up to PN 400) to match diverse operational thresholds.
Oil & Gas Industry: Upstream, midstream, and downstream pipeline systems handling hydrocarbons, natural gas, and hazardous fluids.
Chemical & Petrochemical Plants: Processing units transporting aggressive, high-temperature, or high-pressure chemical compounds.
Power Generation: Steam lines, boiler connections, and high-pressure feedwater loops in thermal and nuclear power plants.
Water Treatment & Marine Engineering: Large-scale municipal water infrastructure, desalination plants, and offshore marine platforms requiring robust corrosion resistance.
